Client/Server Workgroup with a Single Switch

Figure 1-8 illustrates a standard conﬁguration in which bandwidth is shared by all attached

devices. The nodes (workstations, hubs, and servers) in the workgroup are divided into

smaller groups to increase the bandwidth available to each of them and to improve server

response time. Grouping servers in a centralized location can provide beneﬁts such as

security and easier maintenance.

Network resources (such as web and mail servers) are connected to the 100BaseT ports on

the Catalyst 1900 switch, allowing 100-Mbps throughput to users when needed. When the

switch and server ports are conﬁgured for full-duplex operation, the links provide

200 Mbps of bandwidth.

Bandwidth-intensive workstations, such as computer-aided design (CAD) users or other

power users, are connected to the switch 10BaseT ports for their own 10-Mbps bandwidth

access to servers. Single workstations, conﬁgured for full-duplex operation, receive

20 Mbps of dedicated bandwidth from each switched port.

Other workstations are connected to 10BaseT hubs, which provide 10-Mbps shared

bandwidth to users with multiple workstations or to workgroups that require minimal

network bandwidth. These workstations share the available 10-Mbps of bandwidth

available from the switched link. Because hubs run only in half-duplex, each connected port

provides 10 Mbps of bandwidth.

Connecting a router to a 100BaseT switch port provides multiple, simultaneous links to the

Internet through one line.
